#openstack-nova - 2017-04-13
23:01:25 mriedem dansmith: yeah i totally agree
23:01:39 mriedem dansmith: i never knew that existed until about a year ago when laski pointed it out
23:01:45 mriedem ^ is generally my story for everything
23:01:46 claudiub|2 well, it is a bit cloud-y lately
23:01:51 melwitt laski, that rascal
23:03:29 claudiub|2 also, i've submitted the sr-iov bp: https://blueprints.launchpad.net/nova/+spec/hyperv-sriov no implementation yet i'm afraid, apparently there's a whole guide to follow just to configure the nics properly.
23:04:24 mriedem claudiub|2: sounds about right
23:04:31 mriedem claudiub|2: do you get a long weekend?
23:05:05 claudiub|2 well, technically i'm free on monday, i'll still be around
23:05:16 claudiub|2 i don't like vacations too much. :D
23:05:23 mriedem you can read the sriov manual
23:05:42 claudiub|2 yeah, that is in my plan. :D
23:06:14 claudiub|2 and question: can we live-migrate vms with sr-iov?
23:06:19 mriedem claudiub|2: no
23:06:23 mriedem resource tracker issue
23:06:24 claudiub|2 hm, interesting
23:06:26 mriedem *issues
23:06:31 mriedem cfriesen knows about it
23:06:40 claudiub|2 is that a nova limitation, or a hypervisor limitation?
23:09:47 claudiub|2 so, alaski is like beetlejuice - say his name too many times and he shows up. :D
23:10:53 alaski I'm glad I appear to have explained things to folks in the past, because I don't remember much these days
23:15:26 melwitt you missed out on some cerebral shelve feature talk today
23:20:37 alaski I hope it was good. I am very much not proud of introducing that feature.
23:25:38 melwitt hm ... define good. mriedem found that upon shelve offload, volumes are not disconnected and then also when network is cleaned up, that only does something for nova-net through the network_api, the neutron implementation is a no-op pass
23:27:00 melwitt so it pretty much relies on the unshelve putting the instance back on the same host it was shelved offloaded from, which seems really unlikely
23:29:15 alaski yeah, I would not expect that to happen much in practice
23:33:17 gmann mriedem: thank i almost forgot about that bug, ll check patch
23:37:04 cfriesen claudiub|2: the first issue is that we need to get resource tracking in general working over live migration. (see https://review.openstack.org/#/c/244489 and the follow-on patches)
23:39:23 cfriesen do people actually use shelve? If so, why hasn't anyone noticed this?
23:40:22 alaski maybe not using volumes, or neutron?
23:40:41 alaski it did seem to have a small following, despite discouragement about using it
23:42:53 melwitt yeah, I would guess similar. I have heard of it being used and it would work fine for nova-net and no volumes
23:53:20 mriedem cfriesen: someone has, long time ago
23:53:23 mriedem the stratoscale guys
23:53:26 mriedem from the bug in the ML
#openstack-nova - 2017-04-14
00:03:10 gmann mriedem: just replied, i think we need version bump otherwise it will be interop issue
00:04:00 gmann mriedem: cloud with >2.20 may or may not have this fix and it end up with different API behavior on clouds.
00:05:00 gmann mriedem: we could have avoided version bump by backporting fix since 2.20 was in but that was before mitaka which is EOL now
00:05:33 mriedem gmann: then we backport the fix
00:05:45 mriedem we've fixed regressions caused by microversions in the past and backported them
00:10:17 gmann mriedem: and for mitaka?
00:10:29 mriedem gmann: we have all kinds of latent bugs that go back to releases that are long end of life by now
00:10:45 mriedem just because we can't backport something to the release that introduced the bug doesn't mean we can't fix it and backport to what's supported
00:13:19 openstackgerrit Takashi NATSUME proposed openstack/nova master: Add a functional test for 'removeFloatingIp' action https://review.openstack.org/453026
00:13:34 gmann mriedem: yea we can do for supported branches one but my concern with cloud (mitaka) and cloud(mitaka+) where app/sdk would face different behavior issue even both cloud have >2.20 version
00:16:39 mriedem honestly i don't really see this as something to worry about
00:16:46 gmann alex_xu: can we get rid of ALIAS also now? - https://review.openstack.org/#/c/456478/1
00:16:47 mriedem if you have a volume attached before 2.20
00:16:59 mriedem and mountpoint isn't in there, it's completely bonkers
00:17:08 mriedem so i don't even know why that check is in there in the the first place
00:17:30 mriedem i really don't think we should bend over backward and create a new microversion for a thing in the API that makes really no sense to be validating on
00:17:38 mriedem we're raising a 404 for something when we actually found the attachment
00:18:01 gmann yea i also confused about check, it could have just ignore 'device' or None
00:20:00 mriedem gmann: that check goes way back 5 years https://review.openstack.org/#/c/7406/
00:20:06 mriedem and for all intents and purposes, made no sense
00:22:25 gmann mriedem: yes and not sure why it was done for SHOW only and LIST just skip mountpoint.
00:22:25 openstackgerrit Takashi NATSUME proposed openstack/nova-specs master: Abort Cold Migration https://review.openstack.org/334732
00:25:35 gmann mriedem: i understand your point of fixing it for shelve offload at least where it will always 404 but m still worried about this fix discoverability as it change API code
00:28:36 gmann mriedem: but yes backporting makes good reason to avoid version bump if everyone is fine with that
00:35:36 takashin Nova-spec cores, would you review https://review.openstack.org/#/c/407237/ ? It got one +2.
00:41:25 Qeas Hi everyone, I have a problem with block device mappings in my environment and would really appreciate any advice on this. The problem: iSCSI mappings have changed on the backend, though the data is untouched. All the VMs were shutdown before that. Is there a way for Nova to re-attach those same volumes but with their new iSCSI LUNs? I was thinking of cleaning connection_info in mysql, but scared of consequences.
